Abstract

The invention provides a photo-reactor for wastewater / sewage treatment and a wastewater / sewage treatment integrated device. The wastewater / sewage treatment integrated device comprises a membrane bioreactor and the photo-reactor with a water outlet connected with a water inlet of the membrane bioreactor. The photo-reactor comprises a transparent casing provided with a water inlet and a water outlet and a photoreaction unit fixed in the transparent casing, wherein the photoreaction unit comprises an absorbing carrier and a photochemical catalyst loaded on the absorbing carrier. The wastewater / sewage treatment integrated device can perform deeply treat discharged water reaching to the discharge standard through the treatment to obtain recycled water, can also directly treat wastewater / sewage which is not treated, and is good in treatment effect and stable in quality of discharged water. The wastewater / sewage treatment integrated device only comprises the photo-reactor and the membrane bioreactor and is compact in structure, reasonable in link, low in power consumption, small in occupied area and low in operation cost.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a photoreactor for waste / sewage treatment and a waste / sewage treatment integrated device. Background technique [0002] Saving resources and protecting the environment is a basic national policy of our country. With the gradual depletion of water resources, the society pays more and more attention to the governance of water environment and the recycling of water resources. Among them, the reuse of wastewater can not only realize the recycling of water resources Utilization is also one of the important ways to achieve emission reduction. The Twelfth Five-Year Plan puts forward the goal of achieving a 10% recycling rate of urban waste / sewage treatment in cities across the country. According to the 10% recycling rate of waste / sewage, more than 7 billion m of fresh water resources can be saved every year. 3 , can effectively alleviate the problem of water shortag...
